Salty oceans provide early warning for climate change
...ver very short time-scales, usually in less than a decade or two. Ocean water cant possibly travel this fast (it takes nearly a century for a parcel of water to move from the South Atlantic to the North Atlantic). Instead the scientists think that energy is transferred through the ocean along a deep pressur...Candidate research sites selected for the National Ecological Observatory Network
For more than a decade ecologists have wanted to create an observatory for understanding complex ecological processes at multiple scalesfrom continental-scale biosphere dynamics to the microorganisms in soil and water. Now they are preparing to build it. Since 2005, desi...Stray penguins probably reached northern waters by fishing boat
...dinavia, the researchers noted, but after nearly a decade all the penguins had been killed by predators, died by other means or disappeared. Northern sightings of penguins in the wild have been rare. There was a report of a single Humboldt penguin off British Columbia's Queen Charlotte Islands in 1944; o...Lessons from the orangutans: Upright walking may have begun in the trees

"But Yersinia has maintained YpkA over millions of years, so it must be doing something important."

Using networks of GPS receivers that routinely gauge deformation in plate boundary zones around the world, scientists find that pla...IMS updated recommendations on postmenopausal hormone therapy
INTRODUCTION The past decade has seen marked fluctuations in opinions concerning the merits and risks of postmenopausal hormone therapy. In July 2002, menopause management faced a major turning point when the first data from the Womens Health Initiative (WHI) trial were released...Soy estrogens and breast cancer: Researcher offers overview

Much of his work has focused on a single isoflavone, genistein, which occurs in varying concentrations in soy products or ingredients such...Woods Hole Research Center scientists using remote sensing tools to predict bird species richness
